Depending on the outcome of our detailed design, there might be a need for concrete counter-weights connected to the Main girder.
根据详细设计的结果，可能需要在主梁上加混凝土配重。

In order to reduce or eliminate such vibration, it must be provided with counter balanced weights that extend radically from the crankshaft centerline in the opposite direction of the crank arms.
为了减少或降低这种震动，需要把平衡重量从曲轴中心线沿着曲轴臂相反方向安置其上。

A practical method for approximate shaking force balancing of spatial linkages is proposed by attaching counterweights to frame pivoted links.
